[0019] like Figure 1-4The locking mechanism of a reversing switch fixing plate shown in the figure comprises a workbench 1, a processing table 11 is arranged on the workbench 1, a workpiece slot 12 is arranged on the processing table 11, and a locking mechanism, the locking mechanism comprises a limit block 2, a pre-folding block 3 and a forming block 4, the limit block 2 is slidably arranged on the front side of the workpiece slot 12, a slot 21 is arranged at the tail of the limit block 2, a driving block 22 is arranged in the slot 21, the driving block 22 is driven to slide by a first cylinder 23, a curved groove 24 is arranged on the driving block 22, a first connecting shaft 25 is slidably arranged in the curved groove 24, and the first connecting shaft 25 Fixed in the slot 21, the pre-folding block 3 is slidably arranged on the left and right sides of the workpiece slot 12, the pre-folding block 3 is driven to slide by the second cylinder 31, the forming block 4 is slidably arranged on the rear side of the workpiece slot 12, a connecting rod 5 is arranged through the workbench 1, the connecting rod 5 is connected to the rotating shaft of the workbench 1, waist-shaped holes 51 are arranged at both ends of the connecting rod 5, a second connecting shaft 52 is slidably arranged in the waist-shaped hole 51 at the upper end, the second connecting shaft 52 is fixed to the tail of the forming block 4, a third connecting shaft 53 is slidably arranged in the waist-shaped hole 51 at the lower end, and the third connecting shaft 53 is driven and connected to the third cylinder 54.

[0020] Preferably, a fixing seat 13 is provided at the connection between the workbench 1 and the connecting rod 5 , and the rotating shaft of the connecting rod 5 is connected to the fixing seat 13 .

[0021] Furthermore, the third connecting shaft 53 is fixed on the connecting block 55 , and the connecting block 55 is fixed to the driving end of the third cylinder 54 .

[0022] Furthermore, a fixing plate 14 is arranged on the workbench 1 corresponding to the outer side of the connecting rod 5 , and a limiting bolt 15 is passed through the fixing plate 14 , and the limiting bolt 15 abuts against the outer wall of the connecting rod 5 .

[0023] The present invention mentions a reversing switch fixing plate locking mechanism. During the locking process, the metal cover plate workpiece is placed into the workpiece groove 12, and a one-time locking molding process is performed on it between two processes through the locking mechanism arranged thereon.

[0024] When the metal cover is placed in the middle of the workpiece slot 12, the first cylinder 23 is started to control the driving block 22 to slide left and right. As the driving block 22 slides, the first connecting shaft 25 slides synchronously in the curved groove 24 on the driving block 22. Due to the curved path of the curved groove 24, the first connecting shaft 25 drives the limit block 2 to which it is connected and fixed to slide back and forth, thereby achieving placement limit for the head of the metal cover placed in the workpiece slot 12.

[0025] Next, the second cylinder 31 is started to control the pre-folding blocks 3 on both sides to move forward synchronously, so as to perform the first process of pressing and locking the metal sheets on the left and right sides of the metal cover plate after the limited placement. Then, the third cylinder 54 is started to push the connecting block 55 at its driving end to extend and retract forward and backward, so that the third connecting shaft 53 on the connecting block 55 slides in the path of the waist-shaped hole 51 at the lower end of the connecting rod 5, and the movement of the third connecting shaft 53 in the waist-shaped hole 51 at the lower end of the connecting rod 5 can realize the push of the connecting rod 5, so that it swings around the position of the rotating shaft connection point between the middle part and the fixed seat 13. When the connecting rod 5 swings, the second connecting shaft 52 in the waist-shaped hole 51 at the upper end thereof slides synchronously in its path, thereby driving the forming block 4 connected and fixed thereto to move forward on the workpiece groove 12, thereby realizing the forming and locking processing of the end of the metal cover plate placed in the workpiece groove 12, and then completing the second processing process. Finally, the reversing switch with the metal cover locked can be taken out by controlling the limit block 2, the pre-folding block 3 and the forming block 4 to slide and reset.
